Hello everyone,
As per my understanding of the topic, Product Backlog Grooming is of two kinds -
1. User Stories that are going to be part of the Sprint are groomed in the Sprint Planning Meeting.
2. User Stories, in general, are groomed in the Backlog Grooming meeting. This meeting has no official sanction in the official Scrum Guide and is not a timeboxed event.
Is my understanding right? If yes, please let me know when this Backlog Grooming meeting should be conducted and for how long. If no, please clarify.
